Abstract: In response to the rise of “The End of Utopia” discourse and the obstacles to the development of his capitalist ecological critique,William Leiss drew on the essence of utopian ideas from works like Utopian Island,Bensalem,and The Land of Nowhere.He shifted his research focus to the field of science-fiction utopian critique.In The Herasaga,Leiss uses character portrayal to reveal and critique the anti-ecological nature of capitalism,while constructing the “Yucca Settlement” to depict and explore the ideal vision of harmonious coexistence between humanity,technology,and nature in an ecological socialist society.Leiss's main theoretical contributions to green utopian science fiction critique are twofold:First,he defends the theoretical value of utopian thought within the context of “The End of Utopia” discourse,imbuing it with the spirit of capitalist ecological critique.Second,in a world increasingly constrained by capitalist ideology,he challenges the dominant position of capitalist ideology through utopian science-fiction critique,further deepening the multidimensional critique of capitalism.However,in exploring solutions for capitalist technological transformation,Leiss fails to fully break free from the logic of capitalism,which constitutes a limitation of his green utopian science-fiction critical theory.

Key words: William Leiss, capitalist critique, green utopia, science-fiction critique
